Would you say it’s mass hysteria to say Harris would take away our right to vote?
Rigged elections are infringing on the voting process and thus our democratic way of electing public officials. This is going on now.
There is a possibility electing Harris could evolve into a totalitarian regime. Such regimes determine who gets to run for office as well as rigged elections. Right now the democrats are doing their very best to eliminate Trump from running. So in essence they are trying that now.
The answer to your question is yes, another democrat be it Harris or another could cause our democracy to fully crash.
With it goes the Constitutional Republic.
